PUTTING TRAINING DEVICE AND PUTTER WITH THE SAME

FIELD OF THE INVENTION

[0001]The invention pertains to a putting training device designed to facilitate the practice of golf putting. It further encompasses a putter consisting of at least one putter head, one putter shaft, one putter grip, and one putting training device.

BACKGROUND OF THE INVENTION

[0002]Putting training devices, as well as putter equipped with such devices, are known in prior art and are commonly used to practice putting when playing golf. Existing solutions generally focus on two key aspects: the precise alignment of the putter head with the golf ball to improve aim, and the execution of the correct pendulum movement when putting. One such example is disclosed in CN 101 342 419 A, which describes a training device wherein a golf ball is suspended by a thread or chain, with a magnet positioned beneath it. However, the structure of this training device is relatively complex.

[0003]Another way to practice the correct swing is known from U.S. Pat. No. 5,895,328 A, in which centrifugal forces generated by the swing are measured using the swing training device disclosed therein.

[0004]Various types of training devices for improving aim are described, for example, in WO 2018/069 695 A1, US 2019/0269991 A1, U.S. Pat. Nos. 9,943,743 B1, 4,167,268 A, 4,174,838 A, 4,953,867 A, and 5,509,657 A. In some cases, a camera is also used to assist in this process, as disclosed in U.S. Pat. No. 8,608,595 B2. The use of a magnifying device is also known in prior art, as disclosed in the above-mentioned patent WO 2018/069 695 A1. All of the above-mentioned training devices are attached to the respective putter shaft of the putter. All of the above-mentioned training devices are relatively complicated in design and, in some cases, not easy to use.

[0005]Another training device known from prior art is disclosed in U.S. Pat. No. 5,725,441 A. According to this prior art, an additional golf ball is positioned in a recess on the putter head of the putter. The ball positioned on the putter wobbles or tumbles or is knocked out or comes out of the recess if the putter stroke is accelerated or decelerated too quickly. However, this solution proves to be disadvantageous because a putter designed specifically for training must be purchased. Retrofitting an existing putter suitable for regular play and training is not possible with this state-of-the-art solution.

SUMMARY OF THE INVENTION

[0006]The present invention is therefore based on the task of providing a putting training device for practicing putting and a putter with such a device, which, on the one hand, can be manufactured more cost-effectively than solutions of prior art and, on the other hand, can be retrofitted to an existing putter, and which makes it possible to train a player to use a correct pendulum motion when putting with an optimal rhythm and to avoid bending or angling the wrists when putting.

[0007]The task of creating a putting training device for providing putting training is solved in that the putting training device consists of at least one support device with at least one recess-like support surface for placing a rollable object and at least one fastening device for detachably fastening the putting training device to a putter shaft of a putter, and at least one angle adjustment device for adjusting the angle of inclination of at least one support device relative to at least one fastening device, wherein the angle adjustment device is arranged between at least one support device and at least one fastening device. For a putter with at least one putter head, at least one putter shaft, and at lease tone putter grip, the task is solved by the putting training device being detachably attached to the putter shaft of the putter via at least one fastening device and by at least one angle adjustment device adjusting the angle of inclination of the putting training device relative to the putter shaft of the putter. Further developments of the invention are defined in the dependent claims.

[0008]This creates a putting training device for practicing putting that can be easily attached to an existing putter using at least one fastening device. It is therefore not necessary to purchase a separate training putter to practice putting. At least one recess-like support surface of at least one support device, on which a rollable object, such as a golf ball, can be placed, permits the correct pendulum motion when putting and thus allows a player to be trained to use the optimal rhythm and the positioning or angling of the wrists when putting to be avoided. The angle of inclination of the support device for placing a rollable object can be individually adjusted to suit the respective putter. Putters from different manufacturers have different angles of inclination between the putter shaft and the putter head. The putter training device can be adapted very quickly to these different angles of inclination by changing the angle of inclination of at least one support device relative to at least one fastening device of the putter training device. At least one support device with at least one recess-like support surface for placing a rollable object can therefore be arranged approximately horizontally in relation to the orientation in space after attaching the putter training device to the putter shaft of a putter in a basic position of the putter during play and also during training. In addition, the putter shafts of putters for people of different heights can have different lengths and, accordingly, can also have different angles of inclination relative to a vertical or horizontal plane in space during play and training. Adjustment to these different angles of inclination can also be easily achieved by changing the angle of inclination of at least one support device relative to at least one fastening device.

[0009]The putting training device can be detachably attached to an existing putter in an individually desired position on the putter shaft via at least one fastening device. For putting training, the putting training device can thus be attached to the existing putter. For regular play, the putting training device can also be easily removed from the putter again. This proves to be particularly advantageous compared to the specially designed training putter according to U.S. Pat. No. 5,725,441 A.

[0010]A rollable object, such as a golf ball, is placed on at least one recess-like support surface of at least one support device of the putting training device. In particular, at least one support device can be aligned with regard to its angle of inclination by means of at least one angle adjustment device and fixed at the desired angle of inclination. If the pendulum movement during putting is performed too quickly or if there is an abrupt deceleration, the rollable object, in particular the golf ball, falls off the recess-like support surface of at least one support device of the putting training device.

[0011]This allows the person practicing putting, i.e., the golfer, to immediately notice errors in the pendulum motion and thus optimize the pendulum motion and rhythm. Furthermore, the person practicing putting or the golfer can also practice avoiding bending or angling the wrists, since if the wrists are bent or angled, the rollable object, in particular the golf ball, also falls off the recess-like support surface of at least one support device of the putting training device. The person practicing putting or the golfer can thus immediately recognize incorrect angling of their wrists and practice correct wrist alignment.

[0012]It is advantageous for at least one support device and at least one fastening device to be connected to each other via at least one angle adjustment device. This makes it possible to provide only very few components, i.e., to optimize the number of components of the putting training device. This results in a simply constructed, yet highly effective putting training device that can be optimally adjusted to individual needs.

[0013]It is also advantageous if at least one fastening device consists of at least one clamping device with at least two clamping jaws, in particular rounded clamping jaws, for clamping around the shaft of a putter to which the putting training device is or will be attached. The provision of such a clamping device, which fits optimally around a putter shaft and can be clamped around it or attached to it, enables quick and easy attachment to the putter shaft on the one hand, and simple and therefore quick and easy removal from it on the other hand. Of course, instead of a clamping device, in particular instead of the clamping device described above, any other type of fastening device can also be provided for fastening or detachably fastening the putting training device to the shaft of a putter to be equipped with the device.

[0014]In order to prevent the putting training device attached to the shaft of a putter from slipping relative to the putter shaft or along the putter shaft, particularly when swinging the putter while practicing putting, it is also advantageous for at least one fastening device to be provided with or to be equipped with at least one anti-slip device. At least one anti-slip device can, for example, be designed as an insert arranged or inserted in the area of at least one clamping device. Such an insert can be arranged on the inside of at least one clamping device and thus rest on the outside of the putter shaft when the putting training device is mounted on the putter shaft. At least the surface of the insert facing the putter shaft of the putter can be designed to be slip-resistant and/or adhesive, so that high static friction is generated and unwanted slipping of the fastening device along the putter shaft of the putter can be prevented. To form at least one slip-resistant device, at least one clamping device can also be designed as a two-component part. This allows, for example, at least one piece of more stable material to be inserted or placed on the outside of at least one clamping device and at least one piece of slip-resistant or adhesive material to be inserted inside at least one clamping device. The inside of the clamping device engages directly with the outside of the respective putter shaft of a putter to which the putting training device is attached via its at least one fastening device. By adding at least one piece of slip-resistant or adhesive material to the inside, slipping of the fastening device of the putting training device along the putter shaft of the putter can be prevented.

[0015]At least one support device of the putting training device can be polygonal when viewed from above, in particular quadrangular. At least one recess-like support surface of at least one support device can also be designed to be essentially uniformly rounded. By providing the essentially uniformly rounded recess-like support surface, it is possible to allow the rolling object placed on it, for example a golf ball, to roll evenly in all directions. When combining such a recess-like support surface of at least one support device with a polygonal design of the support device when viewed from the top, flattened corner areas remain in the corners of the support device, which thus have no curvature on the upper side. In the side sections of the polygonal support device located between the corner areas, the recess-like support surface can extend to the edge of the support device. This makes it possible to design the side areas, where the rolling object, such as a golf ball, can fall out of the recess-like support surface, lower than the corner areas. The corner areas of the support device are thus advantageously higher than the side sections of the support device located between them, so that errors in the pendulum movement when putting directly cause the rolling object to roll off the support device in these lower side sections between the corner areas of the support device and fall down. Since the side sections of the support device are arranged above the putter head of a putter and approximately parallel to its front side after the putting training device has been mounted on a putter shaft of a putter, the correct stroke and thus the correct pendulum movement can be practiced with the putting training device. A rhythmic pendulum motion of the putter causes the rollable object, in particular a golf ball, not to leave at least one recess-like support surface of at least one support device of the putting training device during the backward and forward motion of the putter. However, when there is a non-rhythmic pendulum movement, the moment of inertia of the rollable object causes it to fall off at least one support surface of at least one support device of the putting training device.

[0016]In addition, at least one support device and at least one fastening device may each have at least one joint section for forming a joint between at least one support device and at least one fastening device for connecting at least one support device to at least one fastening device. At least one angle adjustment device may further advantageously be arranged in the area of the joint or in the joint formed by at least one support device and at least one fastening device. In particular, at least one angle adjustment device may consist of a bolt or pin as the axis of rotation of the joint. It is thus possible to provide only at least one support device and at least one fastening device, each of which has at least one joint section, wherein the joint sections of the support device and the fastening device interlock in such a way that a joint is formed whose axis of rotation is formed by a bolt or pin of at least one angle adjustment device. In particular, the angle adjustment device can form the axis of rotation of the joint formed by the support device and the fastening device. The number of components of the putting training device can thus be further optimized. The putting training device is therefore advantageously not prone to errors and can be easily handled and, in addition, can be manufactured inexpensively compared to solutions of prior art due to the very few components, and at the same time can optimally be individually adapted to a person using the putting training device and their putter.

[0017]A further advantage is that at least one support surface of at least one support device can be provided with at least one alignment mark, in particular at least one slot-shaped alignment mark, for aligning the putting training device parallel to the head of a putter to which the putting training device is attached or is to be attached. In particular, at least one alignment mark may be arranged along a longitudinal axis of the putting training device. This makes it possible to arrange the putting training device in a manner that is exactly aligned above the putter head of the putter to which the putting training device is attached, or aligned with its longitudinal axis and/or parallel to its front side. Correct alignment of the support device relative to the putter head makes it possible to optimize the training conditions with regard to the putting training device and the putter.

[0018]The putting training device can be positioned at a distance from the putter head on the putter shaft, in particular it can be attached to the putter shaft at approximately half its length. This positioning allows for optimal training, as the putting training device does not obstruct the view of the putter head on the one hand, nor does it interfere with the grip on the putter shaft on the other.

DETAILED DESCRIPTION OF THE INVENTION

[0028]FIGS. 1, 3, 4, 7, and 8 show a putter 1 with a putter head 10, a putter shaft 11, and a putter grip 12. A putting training device 2 is arranged on the putter shaft 11 of the putter 1. As can be seen in particular in FIGS. 3 and 4, it is positioned approximately halfway along the length L of the putter shaft 11 and attached to it. In principle, it can of course also be arranged at another position along the putter shaft 11. This is shown in FIGS. 7 and 8. There, it is positioned closer to the putter head 10. If necessary, positioning approximately halfway along the length L of the putter shaft 11 may prove to be the optimal position for practicing putting using the putting training device 2, as the person practicing, i.e. the golfer, can still see the putter head 10 very well despite the putting training device 2 being arranged on the putter shaft 11, and it is also still possible to grip the putter handle 12 without any problems. However, both of these things are also still possible with the positioning shown in FIGS. 7 and 8.

[0029]The putting training device 2 is shown in detail in FIG. 2 and FIGS. 5 and 6. It consists of a support device 20, a fastening device 21, and an angle adjustment device 22. The angle adjustment device 22 is used to change the angle of inclination β of the support device 20 relative to the fastening device 21 and, after fastening the putting training device 2 to the putter shaft 11 by means of the fastening device 21, also relative to the putter shaft 11. This makes it possible to set a horizontal alignment in space, indicated by the horizontal line w in FIG. 4, for the support device 20 of the putting training device 2. The angle of inclination β is measured between the underside 218 of the support device 20 and a longitudinal axis A21 of the fastening device 21. Since the fastening device 21 is fastened to the putter shaft 11 of the putter 1 and its longitudinal axis A21 then extends along the longitudinal axis A11 of the putter shaft 11, the support device 20 is also inclined at the angle of inclination β relative to the longitudinal axis A11 of the putter shaft 11 after the putting training device 2 has been attached to the putter shaft 11 of the putter 1 (see, for example, FIG. 4).

[0030]In addition, the putter head 10 and the putter shaft 11 form an inclination angle α. This may vary from manufacturer to manufacturer. It also varies from one putter 1 to another, depending on the length L of the putter shaft 11, which is adapted to the body length of a person or golfer, and is therefore also dependent on the length L of the putter shaft 11. This variance in the inclination of the putter shaft 11 is indicated in FIG. 4 by the double arrow P1.

[0031]The angle adjustment device 22 of the putting training device 2 makes it possible to set different angles of inclination α between the putter head 10, in particular measured at its lower support surface 13, and the putting shaft 11 by adjusting the angle of inclination β between the support device 20 and the fastening device 21 of the putting training device 2, in order to always enable a roughly horizontal alignment of the support device 20 in space when in the usage position, i.e., the normal playing and training position of the putter 1. In such a horizontal alignment in space, a rollable object 3 placed on the support device 20 of the putting training device 2, for example, a golf ball, as indicated in FIG. 3, cannot roll off the support device 20. The support device 20 of the putting training device 2 can thus be aligned approximately horizontally in a normal playing and training position, depending on the surface, in an alignment approximately parallel to the lower support surface 13 of the putter head 10 and thus also parallel to the ground surface when the lower support surface 13 of the putter head 10 rests on a ground surface. The support device 20 is aligned approximately parallel to the lower support surface 13 of the putter head 10.

[0032]As already mentioned, the angle β of the support device 20 relative to the fastening device 21 of the putting training device 2 can be adjusted using the angle adjustment device 22. As can be seen from the embodiment of the putting training device 2 shown in FIG. 2 and also in FIGS. 7 and 8, the angle adjustment device 22 consists of a threaded bolt 122 and an actuator wheel 222, wherein the threaded bolt 122 is arranged as a pivot axis of a joint 23 between the support device 20 and the fastening device 21 of the putting training device 2. The support device 21 has a joint section 24 and the fastening device 22 also has a joint section 25. The joint section 24 of the support device 21 is U-shaped and accommodates the joint section 25 of the fastening device 22 between its two sides 124, 224, as can be clearly seen in FIG. 2 and FIGS. 7 and 8. The two sides 124, 224 of the U-shaped joint section 24 of the support device 20 and the joint section 25 of the fastening device 22 each have a through-hole 26. In the embodiment shown in FIG. 2 and FIGS. 7 and 8, the through-holes 26 also each have an internal thread that engages with the external thread of the threaded bolt 122. The joint sections 24 and 25 of the support device 20 and the fastening device 21 thus engage with each other, with their through-holes 26 being aligned with each other. The threaded bolt 122 of the angle adjustment device 22 is inserted into the through-holes 26 positioned in alignment with each other. The threaded bolt 122 can be turned by engaging the actuator wheel 222. In the embodiments shown in FIGS. 2, 7, and 8, the actuator wheel 222 has an external profile or corrugation to enable non-slip engagement. An angle of inclination β set between the support device 20 and the fastening device 21 can be fixed by engaging the actuator wheel 222 and turning the threaded bolt 122.

[0033]Because of the design of the joint 23 shown in FIGS. 2, 7, and 8, with the two joint sections 24, 25 of the support device 20 and the fastening device 21 and the formation of the angle adjustment device 22 by the threaded bolt 122 engaging in the through-holes 26 in the joint sections 24, 25, the putting training device 2 consists of only very few components. However, the support device 20 and the fastening device 21 as well as the angle adjustment device 22 can also be designed differently in order to enable an articulated connection of the support device 20 and the fastening device 21 and an adjustment of the inclination angle β between them by means of the angle adjustment device 22. The adjustment of the angle of inclination β is indicated in FIG. 4 by the double arrow P2.

[0034]In the embodiment shown in the figures, the fastening device 21 of the putting training device 2 is designed as a clamping device. In the embodiment shown in FIGS. 1 to 4, it has two rounded clamping jaws 121, 221, a bracket 321, and an actuator strap 421, as can be seen in particular in FIG. 2. The two clamping jaws 121, 221 are pivotably attached to a center piece 521 of the fastening device 21. The center piece 521 is formed integrally with the joint section 25. Likewise, the bracket 321 and the actuator strap 421 are also pivotably attached to the two clamping jaws 121, 221, whereby the actuator strap 421 is also pivotably connected to the bracket 321. The two rounded clamping jaws 121, 221 can be arranged around the outside 14 of the putter shaft 11 and, by pivoting the actuator strap 421 and the bracket 321 connected to it, the putting training device 2 can be clamped in a locking position (see FIG. 1) by pivoting the actuator strap 421 and the bracket 321 connected to it. The clamping fastener can be opened by pivoting back the actuator strap 421 and the bracket 321 of the fastening device 21 connected to it.

[0035]The fastening device 21 of the putting training device 2 also has two rounded clamping jaws 621, 721 in the embodiment shown in FIGS. 5 to 8. However, these each have an actuator lever 622, 722 protruding outwardly away from the clamping jaws 621, 721, as can be seen particularly well in FIGS. 5 and 6. The two actuator levers 622, 722 are connected to the joint section 25 via two compression springs 623, 723. The two clamping jaws 621, 721 are pivotably attached to the center piece 521 of the fastening device 21. By engaging the two actuator levers 622, 722 and exerting a pressure force on them and thus against the spring force of the two compression springs 623, 723, the two clamping jaws 621, 721 can be actuated and pivoted, thereby opening the clamping device. The two rounded clamping jaws 621, 721 can then be arranged around the outside 14 of the putter shaft 11 and secured to it by releasing the two actuator levers 622, 722 and thus by the pressure force exerted by the two compression springs 623, 723 on the two actuator levers 622, 722 and the two clamping jaws 621, 721 of the putting training device 2, as shown in FIGS. 7 and 8. The clamping fastener can be opened by again exerting a compressive force on the two actuator levers 622, 722, thereby opening the clamping device of the fastening device 21.

[0036]In order to be able to attach the fastening device 21 and thus the putting training device 2 to the putter shaft 11 of the putter 1 in a slip-proof manner, the clamping device according to FIGS. 5 to 8 has an anti-slip device in the form of an anti-slip insert on the respective inner side 524, 624, 724 of its two clamping jaws 621, 721 and the center piece 521 of the joint section 25. The anti-slip insert 821 may consist of an anti-slip material, such as a rubber material. In particular, it may have adhesive properties with respect to the surface of the putter shaft 11 and thus have an anti-slip effect. Instead of providing such an anti-slip insert 821, the clamping device can be designed as a two-component part in the area of its two clamping jaws 621, 721 and, if necessary, also of the center piece 521 of the joint section 25. In this case, a softer, anti-slip and/or non-slip material is applied to the respective inner side 524, 624, 724 of the two clamping jaws 621, 721 and, if necessary, also of the center piece 521 of the joint section 25, and a more stable material that provides dimensional stability is provided on the respective outer side. It is then no longer necessary to provide an additional slip-resistant insert, since the clamping jaws 621, 721 in particular are sufficiently slip-resistant for a non-slip engagement with the putter shaft 11 due to their design as two-component parts. The provision of the anti-slip insert 821 or the design of the clamping device, in particular its clamping jaws, as a two-component part to provide an anti-slip device in the area of the fastening device 21 can also be provided in the clamping device in the embodiment according to FIGS. 1 to 4.

[0037]Instead of designing the fastening device 21 as a clamping device, it can also be designed in a different manner. Even when designed as a clamping device, a design other than that shown in FIGS. 1 to 8 can be provided for such a clamping device.

[0038]The support device 20 of the putting training device 2 is polygonal in the top view in each of the embodiments shown in FIGS. 1 to 8, in this case quadrangular. It has four corner areas 201, 202, 203, 204 and, between each two corner areas, there is a side section 205, 206, 207, 208. The support device 20 also has a recess-like support surface 200 on its upper side 209, on which the rollable object 3, such as a golf ball, can be placed, see FIG. 3 and FIG. 8. The recess-like support surface 200 is essentially uniformly rounded and extends to the side sections 205, 206, 207, 208. The corner areas 201, 202, 203, 204 are flattened on their respective upper sides 210, as can also be seen in the figures, in particular FIGS. 2, 5, and 6. The recess-like support surface 200 thus extends only up to the corner areas 201, 202, 203, 204, not into them. As a result, the support device 20 has a greater height in the corner areas 201, 202, 203, 204 than in the side sections 205, 206, 207, 208 lying between them, as can be seen particularly well in FIGS. 2 and 4. Approximately in the middle of its width b, each side section 205, 206, 207, 208 has the smallest height hmin, as can also be seen in FIG. 2.

[0039]The recess-like support surface 200 thus extends in the side sections 205, 206, 207, 208 lying between the corner areas 201, 202, 203, 204 of the support device 20, which is rectangular in this top view, all the way to the edge 214 of the support device 20. It is precisely in these side areas 205, 206, 207, 208 that the rollable object 3, such as a golf ball, can fall out of the recess-like support surface 200 during a non-rhythmic pendulum movement of the putter 1 due to the moment of inertia of the rollable object 3, while the rollable object 3, such as a golf ball, does not leave the recess-like support surface 200 of the support device 20 of the putting training device 2 during a rhythmic pendulum movement of the putter during the backward and forward movements. Errors in the pendulum motion during putting thus directly cause the rollable object 3 to roll and fall off the support device 20 into the side sections 205, 206, 207, 208, which are lower than the corner areas 201, 202, 203, 204. These errors are thus immediately and easily recognizable.

[0040]The recess-like support surface 200 of the support device 20 can be uniformly rounded, i.e., designed like a bowl with the same radius of curvature R at every point. It is also possible to provide at least one area of the recess-like support surface 200 of the support device 20 with a different radius of curvature R, as is shown, for example, in FIGS. 1 and 2 for the innermost area 216 of the recess-like support surface 200. This makes it possible to control the type of pendulum movement at which the rollable object 3 remains on the recess-like support surface 200 and at which it rolls out uncontrollably, for example, after leaving the innermost area 216, which has a different radius of curvature R than the rest of the recess-like support surface 200 and thus initially prevents the rollable object 3 from rolling to the edge of the recess-like support surface 200.

[0041]As can be seen in FIGS. 2, 5, and 6, the recess-like support surface 200 is also provided with a slot-shaped alignment mark 215. This extends along the longitudinal axis A20 center axis of the support device 20 (see FIG. 1). The threaded bolt 122 of the angle adjustment device 22, on the other hand, extends approximately perpendicular to the longitudinal axis A20 of the support device 20, while the longitudinal axis A20 or center axis of the support device 20 extends approximately through the center of the joint 23 of the putting training device 2 and thus through the middle of the two joint sections 24, 25 of the support device 20 and the fastening device 21. The slot-shaped alignment mark 215 makes it possible to align the longitudinal axis A20 of the putting training device 2 parallel to the front side 15 of the putter head 10. A golf ball is struck with the front side 15 of the putter head 10 when putting. Since the rollable object 3 should only roll off the recess-like support surface 200 when the pendulum movement of the putter 1 is not performed correctly or rhythmically, the precise alignment of the putting training device 2 wherein its longitudinal axis A20 is parallel to the front side 15 of the putter head 10, and above the putter head 10, is therefore optimal for training conditions.

[0042]The angle adjustment device 22 thus makes it possible to adjust the angle of inclination β of the support device 20 relative to the fastening device 21 in such a way that, when the putting training device 2 is attached to the putter shaft 11 of the putter 1, its support device 20 is arranged in a horizontal position in space, indicated by the horizontal line w in FIG. 4, provided that the putter 1 is in its playing or training position, as shown, for example, in FIGS. 1, 3, 4, 7, and 8. In the playing or training position, the putter shaft 11 is at an angle γ to the vertical S, in relation to the orientation in a room, which can be adjusted accordingly by changing the angle of inclination β of the support device 20 relative to the fastening device 21.

[0043]In addition to the embodiments of the putting training device for practicing putting described above and shown in the figures, numerous other embodiments can be formed, in particular any combinations of their features, whereby the putting training device always consists of at least one support device with at least one recess-like support surface for placing a rollable object, such as a golf ball, and at least one fastening device for detachably fastening the putting training device to a putter shaft of a putter, and at least one angle adjustment device for adjusting the angle of inclination of at least one support device relative to at least one fastening device, wherein the angle adjustment device is arranged between the support device and the fastening device.
